Door Closer - A door closer is described, which has an output shaft, on which a cam disc is torsion-resistantly disposed, and has a pressure roller. By means of an operational connection, a closer spring presses the pressure roller against a running surface of the cam disc. In relation to an axial center of the output shaft, the pressure roller is disposed such that, during opening or closing of a swing leaf coupled to the output shaft, the pressure roller is movable along a path. Due to the fact that the path bypasses the axial center of the output shaft and on account of the configuration of the running surface of the cam disc, at a respective opening angle of the swing leaf, in different modes of operation of the door closer, a very similar or identical torque is respectively applied to the output shaft.

Automatic Door Shutter - An automatic door shutter is composed of a stationary plate and a pressing plate pivotally combined together to make a resilient body located therebetween. Additionally, a pivot of the stationary plate has a sliding notch accepting an S-shaped resilient sheet abutting the pressing plate. By attaching the stationary plate and sliding base to a door frame and a door board respectively, the resilient body pushes the pressing plate to shut the door board automatically. When the door board is pushing to fully open, the pressing plate pivots to the stationary plate and then the S-shaped resilient sheet slides in the sliding recess and is compressed to deform to become U-shaped one. Until the door board is fully open, the U-shaped resilient sheet causes an outward pushing force to the pressing plate to keep the door board open constantly.
